Rupert Lisburn Gwynne Davies FRSA (22 May 1916 – 22 November 1976) was a British actor best remembered for playing the title role in the BBC's 1960s television adaptation of Maigret, based on Georges Simenon's novels.

In 1940, the pilot of his Swordfish aircraft in which Davies was aboard ditched into the sea off the Dutch coast, following which he was captured and interned in the Stalag Luft III prisoner of war camp.

On his release Davies resumed his career in acting almost immediately, starring in an ex-prisoner of war show, Back Home, which was hosted at the Stoll Theatre, London.

In 1959, he played the role of the Colonel in Alun Owen's The Rough and Ready Lot when it received its stage debut on 1 June 1959 in a production by the 59 Theatre Company at the Lyric Opera House, Hammersmith, as well as in the television adaptation which was broadcast that September.

Davies also played supporting roles in many films, appearing briefly as George Smiley in The Spy Who Came In from the Cold (1965).
